Question 978222
{{{500p - p^2 = 60,000}}}


p is already on one side of the equation.
Left side contains p.
Right side does not contain p.


You would want an expression on one side and 0 on the other side.


{{{500p-p^2+(-60000)=60000+(-60000)}}}
{{{500p-p^2-60000=0}}}
{{{-p^2+500p-60000=0}}}
and maybe for convenience,
{{{(-1)(-p^2+500p-60000)=(-1)0}}}
{{{highlight_green(p^2-500p+60000=0)}}}


Now either complete the square or use formula for general solution of a quadratic equation.  You might be able to factorize without that, but not sure just by looking.
